1.6.4.4 RS485
The serial RS-485 interface (X3) depends on the device model.
The serial RS-485 interface (X3) can be used to connect an external display
device, for example.
The RS-485 connection can be used to connect to another PLC as a Modbus
RTU master or Modbus RTU device. The protocol supports EVEN, ODD, and
NONE parity, as well as 1 or 2 stop bits, and is accordingly in conformity with
the CODESYS serial adapter.
Screened twisted-pair cables must be used.
Configuration: X3 plug connector, 3-pin, spring-loaded plug-in terminal block
